Buying Guide: How to Pick an Apple Watch for Maximum Battery Life
When I’m looking for an Apple Watch that won’t quit on me halfway through the day, my first stop is always the official battery ratings. Apple provides “all-day” estimates, which typically mean about 18 hours of mixed use. But if you want to push beyond that, you need to look at the specific models and their features. The biggest factor for me is the always-on display. Earlier models kept their screen off to save power, but newer ones keep the time visible, which does use more battery. However, the efficiency of the newer chips, like the S8 and S9 SiPs, often balances this out.
Another major consideration is the case material. This might seem minor, but it’s not just about looks. The Apple Watch Ultra and Ultra 2 are in a league of their own, built for extreme adventures with a massive battery that can last up to 36 hours normally, and even 72 hours in a special low-power mode. If you’re a serious hiker, runner, or just someone who hates charging your watch every single night, the Ultra series is your best bet. For most other people, the larger case sizes (45mm or 49mm) generally have slightly better battery life than the smaller ones because they physically have more space for a battery cell.
I also pay close attention to the software features that impact battery. Low Power Mode is a game-changer. It was introduced in watchOS 9 and turns off or limits certain functions like the always-on display, background heart rate readings, and workout reminders to extend your battery life significantly. Not all older Apple Watch models support the latest watchOS versions with this feature, so that’s a key detail to check. Cellular connectivity is another big one. While it’s super convenient for leaving your phone behind, using LTE or 5G will drain your battery much faster than when you’re connected to your iPhone via Bluetooth.
Ultimately, my choice for the best Apple Watch for maximum battery life comes down to balancing my daily needs with my charging habits. If I’m a heavy user who does long GPS workouts and uses sleep tracking, I need the biggest battery I can get. If my usage is lighter—mostly notifications, time, and a short workout—then a standard Series model with a larger case might be perfect. It’s all about matching the watch’s endurance to your lifestyle.
FAQ
Which Apple Watch has the absolute longest battery life?
Hands down, the Apple Watch Ultra 2 and the original Apple Watch Ultra have the longest battery life of any model. Apple rates them for up to 36 hours of normal use. With the introduction of a new low-power setting, you can even stretch that to an impressive 72 hours, which is perfect for multi-day trips or just forgetting your charger for a weekend.
Does the always-on display drain the battery a lot?
Yes, the always-on display does have a noticeable impact on battery life. When this feature is active, the watch has to keep a part of the screen lit and refreshed at all times. If you find your battery is draining faster than you’d like, turning off the always-on display in the Settings app is one of the first things I do to get some extra hours of use.
Can I improve the battery life on my older Apple Watch?
You definitely can. First, make sure you’re running the latest version of watchOS, as Apple often includes battery optimizations. I also go through my notifications and turn off any that aren’t essential. Reducing background app refresh for apps that don’t need it and managing which apps are allowed to use your location can also save a good amount of power throughout the day.
How does Low Power Mode work, and what does it turn off?
Low Power Mode is a setting you can turn on manually or have it prompt you when your battery hits 10%. It limits or turns off several features to extend your battery life. This includes pausing background heart rate and blood oxygen measurements, disabling the always-on display, and making downloads and some wireless connections slower. It’s a great tool for when you need your watch to last just a bit longer.
Is the cellular model worse for battery life?
Absolutely. Using your Apple Watch’s cellular connection (LTE/5G) independently from your iPhone requires more power than staying connected via Bluetooth. If you frequently make calls, stream music, or use data-intensive apps without your phone nearby, you will see a significant reduction in how long your watch lasts on a single charge compared to just using the GPS + Bluetooth model.
What’s the real-world battery life I can expect from a standard Apple Watch?
While Apple quotes an “all-day” 18-hour battery, my real-world experience varies. With a standard Series 9, I can usually get through a full day from 7 AM to 11 PM, including a 60-minute workout, and still have around 20-30% left. Using features like sleep tracking will require a top-up charge at some point during the day, as it’s using power overnight. For most people, the standard models are designed to get you through a typical day, but not much more.
